PIN
Data Bus
: Bi-directional 3-State data bus used to transfer commands, data and status between the DUART and the
Chip Enable
: Active-Low input signal. When Low, data transfers between the CPU and the DUART are enabled on
D0–D7 as controlled by the WRN, RDN and A0–A3 inputs. When High, places the D0–D7 lines in the 3-State
condition.

RxDA
I
Channel A Receiver Serial Data Input
: The least significant bit is received first. “Mark” is High; “space” is Low.
RxDB
I
Channel B Receiver Serial Data Input
: The least significant bit is received first. “Mark” is High; “space” is Low.
Channel A Transmitter Serial Data Output
: The least significant bit is transmitted first. This output is held in the “mark”
condition when the transmitter is disabled, idle or when operating in local loop back mode. “Mark” is High; “space” is Low.
TxDB
O
Channel B Transmitter Serial Data Output
: The least significant bit is transmitted first. This output is held in the ‘mark’
Output 0
: General purpose output or Channel A request to send (RTSAN, active-Low). Can be deactivated
automatically on receive or transmit.
